ABSTRACT:
The lens device includes a lens joined to a lens holder member, the lens holder member having a diverging wall portion that permits suction mounting of the lens device onto a substantially smooth surface. The lens is held by the lens holder member to permit a field of view through the lens and through any surface upon which the lens device is mounted. The lens device is thus conveniently mountable upon the lens of an eyeglass or goggle, the screen of a monitor or radar scope or any other device where it would be beneficial to magnify a selected field of view. Suction mounting of the lens device permits easy removal and relocation of such device on a selected surface or relocation onto an entirely different surface. The lens device is also combinable with an appliance such as a digital stopwatch to provide a module that is suction mountable onto a pair of goggles. A swimmer is thus enabled to keep track of elapsed time while swimming.
